'touch filename.ext' will touch 'filename.ext.exe' or 'filename.ext.lnk' or 'filename.ext.exe.lnk' if they exist when there's no 'filename.ext'

Hi!

Using cygwin 3.3.4-2 and 3.3.5-1:


Create a file named 'file.ext.exe'.

In cygwin, run:

 > touch file.ext


Examine the directory. The 'file.ext' wasn't created; the file 
'file.ext.exe' timestamp was updated.


procmon shows this log for a non-existing file access by touch:
